case study: update on adelaide’s metropolitan rail upgrade
DESCRIPTION
Sevan Simonian, Project Manager Adelaide Metropolitan Rail Upgrade, John Holland Rail delivered this presentation at the 2013 ARA Rail Suppliers Forum. The annual conference is the only event of its kind in Australia which has been specifically researched and developed for the benefit of the rail supply and rail contracting sector.

Adelaide
Metropolitan Rail
Upgrade
Sevan Simonian CEng MICE
Project Manager
A critical part of the SA
Government’s $2B
investment in public
transport infrastructure.
› Design and construction
of rail network
› Belair, Noarlunga and
Gawler Lines
› 6 D&C Contracts in total
› 1 ECI Contract - Facilitate
Adelaide Metropolitan
Rail Upgrade
Why Upgrade?
The Challenges
4
› Highly Compressed Programme – No compromise on
Quality, maintain budget
› Geographic diversity/Community
› Safety and Rail Safety
› Environment
› Interfaces
› Community
4
• Securing Best for Project
Designers & Constructors
• Competing with other large
Projects
•Maintaining Key Personnel for
the life of the Project
Key Points:
Proximity to ARTC

7 7
ECI
› RAMP evolves with the Designs
› Agree Rates and Construction Methodologies
› Agree Risk Sharing
› Independent Estimator engaged from the start
› At 70% design gate, package is converted into lump sum price (AS4300)
› Work packages and concurrent design development and implementation
phases, with subsequent learning implemented in following packages assisting
in early transition
8 8
ECI - Value for Money
› NPV Calculations (Whole of Life)
› Value Engineering
› Innovations
› Risk Assignment and management
› Transition to D&C as early as 30% Design =
Program Savings (Brown Field)
› Operational balance between maintaining
PTSOM Operations with Construction Costs
9 9
Design Strategies
10
› Niche Design Resources, Management,
Review and Verification
› Early 3D Rail Track modelling of the
Alignment Enabled Construction planning
and Interface with other Disciplines
10
• Early Establishment of 3D
Spatial Test Alignment
• Coordinated Input from other
projects in Design
•Designers regularly on track
walks throughout design
Key Points:
Design Strategies – Innovation Recognition
Salisbury Crossover SB3
Moved 400m towards Platform
Allows for Rationalization of the Alignment to
Increase Speed to 100km/hr
Design Delivered as a 3D model
Top ballast
Bottom Ballast
Formation
150mm Capping

Earthworks
› Critical to establish ground preparation
› Geotech engineer design signed off
› Formation treatment must be set and established
› Do not deviate
16
Drainage
› Definitive solutions
17
Track Construction – Point of difference

Planning Considerations
› Client Risks/Expectations
› Programme
› Public Perception
› Risk Mitigation
› Meticulous Planning – fatigue, heat, resources
› UNIMAT
› Mission Command – Empower Engineers & Supervisors
